Theriva Biologics "announced an upcoming poster presentation of new data and subgroup analyses from the VIRAGE Phase 2b clinical trial evaluating VCN-01 (zabilugene almadenorepvec) plus gemcitabine/nab-paclitaxel in newly-diagnosed metastatic pancreatic cancer patients. Tumor reponse, biomarker data, and subgroup analyses are to be presented at the American Association for Cancer Research (AACR) Annual Meeting to be held in San Diego, CA from 17-22 April 2026." "The new data and analyses to be presented at the AACR meeting further reinforce our confidence in the clinical potential of VCN-01 plus gemcitabine/nab-paclitaxel chemotherapy to help metastatic PDAC patients," said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. "Taken together, the tumor response and biomarker data support an immune-mediated mode of action for VCN-01, which is consistent with the previously reported clinical observations, showing that patients treated with VCN-01 plus gemcitabine/nab-paclitaxel experienced a significantly protracted duration of response concomitant with a later-stage prolongation of survival compared to patients treated with gemcitabine/nab-paclitaxel alone. We have achieved alignment with both the FDA and the EMA on a proposed pivotal Phase 3 clinical trial to evaluate multiple doses of VCN-01 plus gemcitabine/nab-paclitaxel in first-line metastatic PDAC patients, and we are planning a small study to assess whether more frequent and extended VCN-01 dosing could further improve outcomes."

About TOVX
Theriva Biologics, Inc. is a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need. The Company is advancing a new oncolytic adenovirus platform. The Company’s candidates are VCN-01, SYN-004 (ribaxamase) and SYN-020. VCN-01, an oncolytic adenovirus designed to replicate selectively and aggressively within tumor cells, and to degrade the tumor stroma barrier that serves as a physical and immunosuppressive barrier to cancer treatment; SYN-004 (ribaxamase) which is designed to degrade certain commonly used IV beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, thereby limiting overgrowth of pathogenic organisms such as VRE (vancomycin resistant Enterococci), and SYN-020, a recombinant oral formulation of the enzyme intestinal alkaline phosphatase (IAP) produced under cGMP conditions and intended to treat both local GI and systemic diseases.
